摘　　要：河南许昌县灵井铁矿床是近几年来在许昌铁成矿区发现的又一个大型铁矿床,属火山-沉积变质型。矿体赋存于登封群武庄岩组二段,矿体主要呈似层状,受太古界登封群武庄岩组控制,矿体与围岩产状一致,受矿区古断隆构造控制,其形态呈北西向带状展布。笔者在研究前人成果的基础上,通过对该区高磁异常特征和矿床地质特征的综合分析,认为该区深部找矿前景较好,矿体沿倾向向深部仍有较大的延伸空间,经进一步深部勘查,可以大幅度提高矿床资源储量。The Lingjing iron ore deposit in Xuchang county, another large-size iron ore deposit in the Xuchang Fe metallogenic region discovered in recent years, is of the ,eolcano-metamorphosed sedimentary type. The ore bodies occur in the 2nd Wuzhuang rock group of the Dengfeng Formation, with stratoid occurrence. Under the control of the 2nd Wuzhuang rock group of the Dengfeng Formation, the ore body and county rock are present conformably. The ancient uplift structures in mining area exert a key control on the rock bodies, which resulted in their zonal NW-trending distribution. Based on previ- ous studies, this paper analyzes the high magnetic anomaly characteristics and geological characteristics of the deposit. It is concluded that this area has a good ore-search prospect toward depth, where tbe orebody may extend along its trend down to depth. And with further exploration toward depth, it is pos- sible to greatly increase the mineral resouree reserve in this area.
